Application of magnesite–bentonite clay composite as an alternative technology for removal of arsenic from industrial effluents

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Marinda Date: Oct 2014 This study evaluated the feasibility of integrating amorphous magnesite and bentonite clay (composite) as an alternative technology for removing arsenic from industrial effluents. The removal of arsenic from industrial effluents by using ... Read more
Fate of inorganic contaminants post treatment of acid mine drainage by cryptocrystalline magnesite: Complimenting experimental results with a geochemical model

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Mar 2016 This study assessed the fate of inorganic contaminants post treatment of acid mine drainage by cryptocrystalline magnesite. To accomplish that, neutralization and metal attenuation were evaluated and complemented with simulations using ... Read more
Kinetics and equilibrium studies for removal of fluoride from underground water using cryptocrystalline magnesite

Author: Masindi, Vhahangwele ; Gitari, WM ; Ngulube, T Date: Sep 2015 In the present study, the defluoridation capabilities and adsorption mechanisms of cryptocrystalline magnesite were evaluated. All experiments were done by batch procedure. Conditions assessed include time, dosage, concentration, pH and the ... Read more
Reclamation of water and the synthesis of gypsum and limestone from acid mine drainage treatment process using a combination of pre-treated magnesite nanosheets, lime, and CO2 bubbling

Author: Masindi, Vhahangwele ; Madzivire, G ; Tekere, M Date: Dec 2018 In this study, an integration of pre-treated magnesite, lime, and CO2 bubbling (MLC) was used for the treatment of acid mine drainage (AMD). The primary aim was to reclaim clean water and synthesize valuable minerals. This treatment process ... Read more
Recovery of drinking water and valuable minerals from acid mine drainage using an integration of magnesite, lime, soda ash, CO(sub)2 and reverse osmosis treatment processes

Author: Masindi, Vhahangwele Date: Aug 2017 In this study, the possibility of recovering valuable minerals and drinking water from acid mine drainage was explored. Neutralisation of Acid Mine Drainage (AMD) and recovery of metals were done at 60 mins of equilibration. DOW water & Process ... Read more
Removal of boron from aqueous solution using magnesite and bentonite clay composite

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Mar 2015 The removal of boron from industrial effluents using the composite was studied in batch equilibration technique. The effects of equilibration time, adsorbent dosage, concentration and pH on removal of boron were investigated. The experiments ... Read more
